SINUMERIK 802D sl/840D/840D sl/840Di/840Di sl/810D ISO Milling (PGM) -- 04.07 Edition

Programming key Characters and character sequences which have a defined meaning

in the programming language

for --> part programs (see Programming Guide).

Protection zone Three--dimensional area within a --> working area which the tool tip

is not permitted to enter (programmable via MD).

Quadrant error

compensation

Contour errors on quadrant transitions caused by frictional

fluctuations on guideways can be largely eliminated by means of

quadrant error compensation. A circularity test is performed to

parameterize the quadrant error compensation function.

R parameter Calculation parameter. The programmer can assign or request the

values of the R parameter in the --> part program as required.

Rail This rail is used to mount the modules of the S7--300 system.

Rapid traverse The highest traversing speed of an axis used, for example, to bring

the tool from an idle position to the --> workpiece

contour or retract it from the workpiece contour.

Reference point Point on the machine tool with which the measuring system of the

--> machine axes is referenced.

Reference point

approach

If the position measuring system used is not an absolute--value

encoder , then a reference point approach operation is required to

ensure that the actual values supplied by the measuring system are

in accordance with the machine coordinate values.
